An aneurysm originating from the junction of the A1 segment of the anterior cerebral artery and accessory middle cerebral artery (Acc-MCA) is markedly rare. We report a rare case of an Acc-MCA aneurysm, and discuss the clinical course and management of this rare condition.
A 64-year-old man with a past history of cerebral infarction was revealed to have a left Acc-MCA and an aneurysm at its origin. The aneurysm was clipped via a transsylvian approach. Due to its location and projectile direction, the neck of the aneurysm was left partially unclipped.
Although an Acc-MCA aneurysm is very rare, it has a potential risk of rupture. Therefore, radical treatment is necessary for such aneurysms.
起源于大脑前动脉A1段与大脑中动脉副支（Acc-MCA）交界处的动脉瘤极为罕见。我们报告一例罕见的Acc-MCA动脉瘤病例，并讨论这种罕见疾病的临床病程及治疗方法。
一名有脑梗死病史的64岁男性被发现患有左侧Acc-MCA及其起始处的动脉瘤。通过经外侧裂入路夹闭动脉瘤。由于其位置和投射方向，动脉瘤的颈部部分未被夹闭。
尽管Acc-MCA动脉瘤非常罕见，但有破裂的潜在风险。因此，对此类动脉瘤进行根治性治疗是必要的。
